The dark side of the American work ethic: widespread sleep deprivation, linked to obesity, depression, even early death

Many Americans are long overdue for a good nap. Their health—and that of the economy—might depend on it.

A rising share of Americans are sleeping less than they should, adding on to the country’s persistent sleep deficit that public health experts say will lead to far worse outcomes than simple grogginess. In 2024, 30.5% of Americans—almost one third—slept on average less than seven hours a night, according to data released last week by the Centers for Disease Control & Prevention.
